Escherichia coli isolated from six calves, in two groups of three which were managed differently and which received no antibiotics, were differentiated into strains on the basis of O serotype, biotype and resistance pattern. Keeping the calves in the maternal environment for 10, rather than 4 d, was associated with a delay in the time taken for strains of E. coli resistant to antibacterial agents to outnumber, in the faeces, those that were sensitive. These findings indicate that the prevalence of resistant E. coli strains in the intestinal microbiota reflect, in part, their prevalence in the environment and that their level may be influenced by the management of the animal.
